It is recognized as redhat2.1. RHEL2.1 is based on RH 7.2 and uses
pthreads. Using a source tree from cvs (CVS checkout at about 2245Z Mar
29, 2005) I created configureextra/LINUXredhat2.1 based on the contents
of configureextra/LINUXredhat8.0.
--- begin configureextra/LINUXredhat2.1 ---
#!/bin/sh
echo " Setting RHEL 2.1 specific flag values"
CPPFLAGS="${CPPFLAGS} -DFORPRENPTL"
--- end configureextra/LINUXredhat2.1 ---
After building it I experimented with the -t option. If I give a value
> 3 the web service does not work. I seem to have the same problem if I
start the SSL server.
If I use "--no-fc -u ntop -d -P /var/ntop -i eth1 -m 172.18.32.0/21
-w3000 -W 0 --disable-schedyield -t3" everything works fine for a while.
I have it running now and will do a gdb traceback the next time I get it
hung up.

2.1 is probably pre NPTL and so you need the work-around for the
syslog()
hang.
Figure out what the configureextra file should be and copy the lines
from
LINUXredhat8.0 (I've posted instructions on this within the last 2
weeks).

I don't know if anyone has succeeded in this, I haven't.
Here is what I have tried so far.
Building from source using Red Hat's libpcap fails during configure
with:
*******************************************************************
*
* ERROR: pcap header, bpf or library routines are missing
* (yes means it was found, no means it was not found)
*
* pcap.h...yes
* net/bpf.h...yes
* pcap-bpf.h...no
* pcap_open_live() in -lpcap...yes
* pcap_findalldevs() in -lpcap...no
*
* (One of the bpf files is required, but either will do)
*
*>>> No way to proceed.
*
*??? 1. Install libpcap (http://www.tcpdump.org/)
*??? and Rerun ./configure
*??? or 2. Use the --with-pcap-root= option
*
*******************************************************************
I grabbed and installed a newer libpcap and tcpdump. I built them as
RPMs. tcpdump sees the interface fine and gives lots of data.
I them built ntop-3.1 against the new libpcap library and install it. I
then edit the ntop.conf file setup the password and then start ntop. It
starts up several threads.
So far, so good.
When I attempt to open the web interface at port 3000 it hung my browser
(Firefox on RHEL4). I stopped all the treads and restarted everything
by
hand under strace.
strace -ff -x -s 80 -o /tmp/ntop.strace /usr/bin/ntop -u ntop -d -P
/var/ntop -i eth1 -m 172.18.32.0/21\
-t7 -w3000 -W 0 --disable-schedyield --use-syslog=local6
The web thread gets hung at rt_sigsuspend. The log entries for this
thread
are:
14:40:22 mon2 ntop[1462]: [MSGID0316203] [webInterface:8869] Note:
SIGPIPE handler set (ignore)
14:40:22 mon2 ntop[1462]: [MSGID0986275] [webInterface:8890] WEB:
ntop's web server is now processing requests) for web server
The only thread that seems to increase in size appears to be a polling
thread.
I built the dev version from CVS with the same results.
Am I running into a known issue or...
